LIQUID CHELATING AGENT

Neocrys Chelate as Liquid Chelating Agent

Metal ions have a powerful influence on chemical processes as well as on the performance of many products. A wide range of problems associated with metal ions can be solved using Neocrys Chelate.

Chelates seize a metal ion and control it, making it very difficult for another substance to liberate it. NEOCRYS chelates form strong, water-soluble complexes that prevent undesirable precipitation, dissolve scale deposits and optimize oxidation processes. Our NEOCRYS chelate product range includes chelating agents that bind and control metal ions, as well as metal chelates.

DIRECTIONS FOR USE :
The following recommendation may serve as a guide 0.5 ~ 1 G/Lt.
The quantity of chelating agent needed depends on the concentration of metal ion to be chelated and the type of NEOCRYS chelating agent used. NEOCRYS® chelating agents form a complex with a metal ion generally on an equimolecular basis (which means the higher the molecular weight of the chelating agent, the higher the quantity of chelating agent required to chelate the metal ion).

APPLICATIONS USED :
Cleaning and Detergents
NEOCRYS chelating agents are powerful builders. They enhance the cleaning power of a cleaner/ detergent by catching the hardwater ions ( Ca and Mg) and removing Ca and Mg based residues which bind most dirt to surfaces.
They also prevent the deactivation of anionic surfactants from hard water metal ions, so less surfactant can be used.
Besides this, what’s more, NEOCRYS chelating agents deactivate the unwanted transition metal ions that are often introduced through raw materials in the manufacture of soap and of detergents that contain peroxides like hydrogenperoxide, percarbonates and perborates.
In biocidal detergents chelates greatly enhances the effectiveness of biocides so the amount needed to be effective can be reduced. They also boost the performance of preservatives in liquid detergents, again less can be used and cost savings can be made.

Industrial Cleaning 
Metal salts can cause scaling problems in boilers, heat exchangers and other water circulation systems found in the power, brewing, sugar and dairy industries. NEOCRYST® chelating agents form stable, water-soluble metal complexes with all potentially harmful metal ions, dissolving existing scale formations and preventing new scales from forming.

Printing ink 
Metal ions can cause the formation of insoluble resin soaps in water thinned inks. For example, in offset printing, the formation of polyvalent metal soaps may cause unwanted discoloration. NEOCRYS® chelating agents are used to overcome these problems, resulting in clear and color-stable inks.

Pulp and paper 
Some transition metal ions catalyze the decomposition of bleaching agents (e.g. peroxide, ozone and hydrosulfite) and can lead to brightness reversion of pulp and paper. Traces of heavy metals, which occur naturally in wood fibers and processing water, work against the best efforts of pulp and paper mills to produce brighter, whiter papers. Uncontrolled, these metal ions reduce the effectiveness of hydrosulfite and hydrogen peroxide bleaches used to brighten pulps. As a result, it takes more bleach to achieve and maintain the desired level of brightness. Because bleach chemicals are relatively expensive, pulp and paper mills have long worked to control metal ions through chelation chemistry.
NEOCRYS® chelating agents are used to remove and deactivate metal ions.

Textiles 
During the scouring and bleaching of textile fibers, NEOCRYS® chelating agents remove and deactivate metal ions that would otherwise catalyze the decomposition of the peroxide bleaching agent. They also improve the performance of dye baths, where metal ions like Ca and Mg inhibit dye penetrating the fiber.
